NASA Television coverage of today’s spacewalk with NASA astronauts Chris Cassidy and Robert Behnken is now underway and available on the agency’s website.

The crew members of Expedition 63 are preparing to venture outside the International Space Station for a spacewalk expected to begin at approximately 7:35 a.m. EDT and last as long as seven hours.

The crew is in the airlock and have put on their spacesuits in preparation to exit the airlock and begin today’s activities working on one of two power channels on the far starboard truss (S6 Truss) of the station.

The primary tasks for today are to install one more lithium-ion battery and one more adapter plate and remove the sixth nickel-hydrogen battery that will no longer be used. The batteries store electricity for one pair of the station’s solar arrays. They also will do some advance work for the final two spacewalks for the battery upgrades, route power and ethernet cables to provide better views on future spacewalks, and release a device in support of future power system upgrades.

Leading the mission control team today is Flight Director Royce Renfrew with support from Jaclyn Kagey as the lead spacewalk officer.
